Level Headed is the sixth album by Sweet. It features "Love Is Like Oxygen", the band's last original single to hit the top 40 on both sides of the Atlantic, peaking at #8 in the US and #9 in the UK. The single version of "Love Is Like Oxygen" is substantially shorter than the album version, and the US version has only the first verse, shorter intermezzo and the funk outro. A second single, "California Nights", was released from the album but only reached #76 in the US.
This was the last album to feature the classic lineup, as Brian Connolly departed around a year after the album's release, in order to embark on a solo career. The remaining trio of Steve Priest, Andy Scott, and Mick Tucker continued as Sweet and delivered three more albums before breaking up in 1981.
Allmusic lauded the album in their retrospective review, praising the wild sampling of styles and the band's shift from their earlier bubblegum singles to album-driven rock. They concluded "Certainly, this is not classic-era Sweet, but that's precisely what's good about Level Headed - they're off-kilter and adventurous, occasionally stumbling but always making interesting music on an album that's anything but what the title promises."
